This driver adds support for Dynamic Platform and Thermal Framework
battery participant device support.
These attributes are presented via sysfs interface under the platform
device for the battery participant:
$ls /sys/bus/platform/devices/INT3532:00/dptf_battery
current_discharge_capbility_ma
max_platform_power_mw
no_load_voltage_mv
high_freq_impedance_mohm
max_steady_state_power_mw
Refer to the documentation at
Documentation/ABI/testing/sysfs-platform-dptf
for details.
Here the implementation reuses existing dptf-power.c as the motivation and
processing is same. It also shares one ACPI method. Here this change is
using participant type, "PTYP" method to identify and do different
processing. By using participant type, create/delete either "dptf_power"
or "dptf_battery" attribute group and send notifications.
The particpant type for for the battery participant is 0x0C.

Add two additional attributes to the existing power participant driver:
rest_of_platform_power_mw: (RO) Shows the rest of worst case platform
power in mW outside of S0C. This will help in power distribution to SoC
and rest of the system. For example on a test system, this value is 2.5W
with a 15W TDP SoC. Based on the adapter rating (adapter_rating_mw), user
space software can decide on proper power allocation to SoC to improve
short term performance via powercap/RAPL interface.
prochot_confirm: (WO) Confirm EC about a prochot notification.
Also userspace is notified via sysfs_notify(), whenever power source or
rest of the platform power is changed. So user space can use poll()
system call on those attributes.
The ACPI methods used in this patch are as follows:
PROP
This object evaluates to the rest of worst case platform power in mW.
Bits:
23:0 Worst case rest of platform power in mW.
PBOK
PBOK is a method designed to provide a mechanism for OSPM to change power
setting before EC can de-assert a PROCHOT from a device. The EC may
receive several PROCHOTs, so it has a sequence number attached to PSRC
(read via existing attribute "platform_power_source"). Once OSPM takes
action for a PSRC change notification, it can call PBOK method to confirm
with the sequence number.
Bits:
3:0 Power Delivery State Change Sequence number
30 Reserved
31 0 – Not OK to de-assert PROCHOT
1 – OK to de-assert PROCHOT
PSRC (Platform Power Source): Not new in this patch but for
documentation for new bits
This object evaluates to an integer that represents the system power
source as well as the power delivery state change sequence number.
Bits:
3:0 The current power source as an integer for AC, DC, USB, Wireless.
0 = DC, 1 = AC, 2 = USB, 3 = Wireless Charging
7:4 Power Delivery State Change Sequence Number. Default value is 0
Notifications:
0x81: (Power State Change) Used to notify when the power source has
changed.
0x84: (PROP change) Used to notify when the platform rest of power has
changed.

Currently, changing the brightness of the internal display of the Acer

Still ACPI backlight control doesn't work on this model, where as the
native (intel_video) backlight interface does work by adding
`acpi_backlight=native` or `acpi_backlight=none` to Linux’ command line.
So, add a quirk to force using native backlight control on this model.

memory_failure() offlines or repairs pages of memory that have been
discovered to be corrupt. These may be detected by an external
component, (e.g. the memory controller), and notified via an IRQ.
In this case the work is queued as not all of memory_failure()s work
can happen in IRQ context.
If the error was detected as a result of user-space accessing a
corrupt memory location the CPU may take an abort instead. On arm64
this is a 'synchronous external abort', and on a firmware first
system it is replayed using NOTIFY_SEA.
This notification has NMI like properties, (it can interrupt
IRQ-masked code), so the memory_failure() work is queued. If we
return to user-space before the queued memory_failure() work is
processed, we will take the fault again. This loop may cause platform
firmware to exceed some threshold and reboot when Linux could have
recovered from this error.
For NMIlike notifications keep track of whether memory_failure() work
was queued, and make task_work pending to flush out the queue.
To save memory allocations, the task_work is allocated as part of
the ghes_estatus_node, and free()ing it back to the pool is deferred.

Flushing the EC work while suspended to idle when the EC GPE status
is not set causes some EC wakeup events (notably power button and
lid ones) to be missed after a series of spurious wakeups on the Dell
XPS13 9360 in my office.
If that happens, the machine cannot be woken up from suspend-to-idle
by the power button or lid status change and it needs to be woken up
in some other way (eg. by a key press).
Flushing the EC work only after successful dispatching the EC GPE,
which means that its status has been set, avoids the issue, so change
the code in question accordingly.

If the EC GPE status is not set after checking all of the other GPEs,
acpi_s2idle_wake() returns 'false', to indicate that the SCI event
that has just triggered is not a system wakeup one, but it does that
without canceling the pending wakeup and re-arming the SCI for system
wakeup which is a mistake, because it may cause s2idle_loop() to busy
spin until the next valid wakeup event. [If that happens, the first
spurious wakeup is still pending after acpi_s2idle_wake() has
returned, so s2idle_enter() does nothing, acpi_s2idle_wake()
is called again and it sees that the SCI has triggered, but no GPEs
are active, so 'false' is returned again, and so on.]
Fix that by moving all of the GPE checking logic from
acpi_s2idle_wake() to acpi_ec_dispatch_gpe() and making the
latter return 'true' only if a non-EC GPE has triggered and
'false' otherwise, which will cause acpi_s2idle_wake() to
cancel the pending SCI wakeup and re-arm the SCI for system
wakeup regardless of the EC GPE status.
This also addresses a lockup observed on an Elitegroup EF20EA laptop
after attempting to wake it up from suspend-to-idle by a key press.

The ID mapping table structure of the IORT table describes the size of
a range using a num_ids field carrying the number of IDs in the region
minus one. This has been misinterpreted in the past in the parsing code,
and firmware is known to have shipped where this results in an ambiguity,
where regions that should be adjacent have an overlap of one value.
So let's work around this by detecting this case specifically: when
resolving an ID translation, allow one that matches right at the end of
a multi-ID region to be superseded by a subsequent one.
To prevent potential regressions on broken firmware that happened to
work before, only take the subsequent match into account if it occurs
at the start of a mapping region.

Per the PCI Firmware spec, r3.2, sec 4.5.1, the OS can request control of
AER via bit 3 of the _OSC Control Field. In the returned value of the
Control Field:
The firmware sets [bit 3] to 1 to grant control over PCI Express Advanced
Error Reporting. ... after control is transferred to the operating
system, firmware must not modify the Advanced Error Reporting Capability.
If control of this feature was requested and denied or was not requested,
firmware returns this bit set to 0.
Previously the pci_root driver looked at the HEST FIRMWARE_FIRST bit to
determine whether to request ownership of the AER Capability. This was
based on ACPI spec v6.3, sec 18.3.2.4, and similar sections, which say
things like:
Bit [0] - FIRMWARE_FIRST: If set, indicates that system firmware will
handle errors from this source first.
Bit [1] - GLOBAL: If set, indicates that the settings contained in this
structure apply globally to all PCI Express Devices.
These ACPI references don't say anything about ownership of the AER
Capability.
Remove use of the FIRMWARE_FIRST bit and rely only on the _OSC bit to
determine whether we have control of the AER Capability.

Where IORT nodes for named components can describe simple DMA limits
expressed as the number of address bits a device can drive, _DMA methods
in AML can express more complex topologies, involving DMA translation in
particular.
Currently, we only take this _DMA method into account if it appears on a
ACPI device node describing a PCIe root complex, but it is perfectly
acceptable to use them for named components as well, so let's ensure
we take them into account in those cases too.
Note that such named components are expected to reside under a
pseudo-bus node such as the ACPI0004 container device, which should be
providing the _DMA method as well as a _CRS (as mandated by the ACPI
spec). This is not enforced by the code however.

into account in combination with the DPM_FLAG_LEAVE_SUSPENDED

Then, neither the PM core nor the middle-layer (sybsystem) code

to be cleared if there is a reason to avoid skipping the "noirq"
and "early" resume callbacks provided by the driver, so update

The current code in device_resume_noirq() causes the entire early
resume and resume phases of device suspend to be skipped for
devices for which the noirq resume phase have been skipped (due
to the LEAVE_SUSPENDED flag being set) on the premise that those
devices should stay in runtime-suspend after system-wide resume.
However, that may not be correct in two situations. First, the
middle layer (subsystem) noirq resume callback may be missing for
a given device, but its early resume callback may be present and it
may need to do something even if it decides to skip the driver
callback. Second, if the device's wakeup settings were adjusted
in the suspend phase without resuming the device (that was in
runtime suspend at that time), they most likely need to be
adjusted again in the resume phase and so the driver callback
in that phase needs to be run.
For the above reason, modify the core to allow the middle layer
->resume_late callback to run even if its ->resume_noirq callback
is missing (and the core has skipped the driver-level callback
in that phase) and to allow all device callbacks to run in the
resume phase. Also make the core set the PM-runtime status of
devices with SMART_SUSPEND set whose resume callbacks are not
skipped to "active" in the "noirq" resume phase and update the
affected subsystems (PCI and ACPI) accordingly.
After this change, middle-layer (subsystem) callbacks will always
be invoked in all phases of system suspend and resume and driver
callbacks will always run in the prepare, suspend, resume, and
complete phases for all devices.
For devices with SMART_SUSPEND set, driver callbacks will be
skipped in the late and noirq phases of system suspend if those
devices remain in runtime suspend in __device_suspend_late().
Driver callbacks will also be skipped for them during the
noirq and early phases of the "thaw" transition related to
hibernation in that case.
Setting LEAVE_SUSPENDED means that the driver allows its callbacks
to be skipped in the noirq and early phases of system resume, but
some additional conditions need to be met for that to happen (among
other things, the power.may_skip_resume flag needs to be set for the
device during system suspend for the driver callbacks to be skipped
during the subsequent resume transition).
For all devices with SMART_SUSPEND set whose driver callbacks are
invoked during system resume, the PM-runtime status will be set to
"active" (by the core).
